Ignored mount points forgotten on reboot

[Kenneth Porter]

<https://wiki2.dovecot.org/Mountpoints>

The list of ignored mount points are stored in a directory (/var/run) 
that's cleared on  reboot. (On CentOS it's a RAM disk.) It seems this 
should be stored in /etc/dovecot to remain persistent across reboots.

I discovered this when I saw a dovecot error message in /var/log/maillog 
that some of my automounts (that don't contain mail directories) were 
missing.

Latest dovecot from this distro is dovecot-2.2.10-8.el7.x86_64. Does the 
new release fix this? (I haven't seen any real problems from it, just log 
noise.)
